Abstract
A chloride-free catalyst for wash-and-wear finishing textiles with formaldehyde-free crosslinking agents contains magnesium and fluoroborate ions in a ratio of from 1:0.1 to 1:4 and guarantees odorless results.
Description
Owing to the persistent controversy about the use of formaldehyde-containing auxiliaries in the textile industry, there is an increasing trend, for example in the wash-and-wear finishing of textiles, toward using formaldehyde-free crosslinking agents, for example those of the formula I ##STR1## where R1 and R2 are each hydrogen or C1 -C3 -alkyl, with the proviso that at least one of the radicals R1 and R2 is C1 -C3 -alkyl, and R3 and R4 are each hydrogen or C1 -C4 -alkyl.
However, it is occasionally observed, in connection with large-scale production in textile processing operations, that the finished material is prone to give off an extremely unpleasant odor, which was not noticed when these crosslinking agents first came on the market. This odor is apparently the result of a catalytic decomposition of the crosslinking agent at elevated (condensation) temperatures, forming highly volatile compounds. The odor nuisance is particularly pronounced in the case of already made-up and airtightly packaged material.
It is an object of the present invention to find a way of avoiding this odor nuisance.
We have found that this object is achieved by a chloride-free catalyst whose use does not give rise to odor nuisance and which contains magnesium and fluoroborate ions in an Mg2 ⊕ :BF4.sup.⊖ molar weight ratio of from 1:0.1 to 1:4, preferably from 1:0.2 to 1:2.
Preferably, the catalyst is used in the form of an aqueous solution which contains from 15 to 40% by weight, preferably from 20 to 35%, of salt. The magnesium and fluoroborate ions may be introduced into such a solution in salt form, for example as magnesium sulfate, phosphate, nitrate, acetate, glycolate, citrate or adipate or as sodium, lithium, potassium or zinc fluoroborate. Particular preference is given to the use of magnesium sulfate, magnesium nitrate and sodium fluoroborate.
The catalyst is used in wash-and-wear finishing in the manner which is usual for example for magnesium chloride; the amounts used range from approximately 30 to 50 parts of a, for example, 20% solution, based on 100 parts of the crosslinking agent (45% solution). The novel catalyst requires no departure from existing methods. Experimental:
A cotton fabric (100 g/m2) is impregnated with a pad-mangle, wet pickup about 80%, with the following solutions:

The finished material was packed airtightly in polyethylene sheeting, stored for 24 hours and then subjected to an odor test.
The samples treated according to Examples 1 to 3 were odorless, those according to Examples 6 and 7 were slightly odorous, and those according to Examples 4 and 5 had an extremely unpleasant odor.
